Take action at www.sierraclub.org/coalash. Right now communities across the country are exposed to heavy metals such as arsenic, lead and mercury when hazardous materials from coal ash disposal sites seep into our drinking water, contributing to serious health problems.. The EPA is holding a public comment period on new, federally enforceable standards to protect Americans, but the coal industry is fighting back, trying to put their profits before our health. Help us give the EPA the support it needs to stand up to King Coal by sending a message at sierraclub.org/coalash
